Description

Division strip for speedy drainage type curved road}

The present invention is a curve that enables the vehicle to operate safely by quickly draining the rainwater generated from the side of the lane with a large radius of rotation due to a single slope in the central separator installed on the curved section such as an automobile road or highway. It relates to a concrete divider for roads.

It is common to install a concrete central separator on the center line of a motorway or highway to prevent vehicle accidents caused by the runway of vehicles. On roads with two or more lanes in one way, the pavement surface of curved sections, in particular, provides a cant toward the roadside of a lane with a small turning radius to improve the driving performance on curved roads.

In this way, if a concrete divider is installed at the center line of a road where the radius of rotation is generally toward the side of the road, this is a barrier that prevents rainwater from flowing into the lane with the smaller radius of rotation. Changes to As a result, the rainwater falling on the lane with the larger radius of rotation accumulates on the central separator and creates a puddle, which causes a problem of water filming on the road, which causes the running vehicle to slip, or is bounced off by the vehicle. The baptism of water jeopardizes the safety of other vehicles running in nearby lanes. Water trapping due to the median separator is prominent in the median section of the curved section constructed continuously. In order to solve this problem, in order to drain rainwater generated in lanes with a large radius of rotation due to a single slope, a rainwater outlet is installed at the lower part of the center separator at a certain interval and connected to the underground drainage pipe connected to the road surface. As it was drained, it was inconvenient because it took a lot of cost and effort for installation period, cost and management.

On the other hand, in the case of a separator made in the form of a unit member, there is a gap between the separators, so that the rain road with a large radius of rotation can flow down to the road with a small radius of curvature. It is easy to give drainage by pouring concrete, but the central separator of the curved main road, which is installed by continuous pouring, is not easy to install by continuously pouring concrete while forming drainage, unlike unit type separator.

In this regard, the center section of the curved section needs to have a drainage means that allows the rainwater with a large radius of rotation to flow down quickly to a lane with a small radius of rotation due to a single slope. In addition, the safety of the vehicle as well as other vehicles passing through the same time zone should be considered.

In addition, when installing the center separator of the curved section by placing concrete continuously, it should be possible to easily form drainage holes at regular intervals without disturbing the continuous concrete placing.

The present invention installs a drain in the lower part of the continuous construction-type central separator installed in the roadway of curved section that can meet these expectations, so that the rainwater side of the large turn radius flows quickly to the lane of the small turn radius. It is to provide a median for fast drainage curve roads that can promote the safe operation of vehicles.

In the continuous construction type central separator (1) for curved roads, such as automobile-only roads or highways, the present invention provides a quick drainage type configured to form a drainage drainage by arranging a drainage drainage frame so as to face the center of the radius of rotation of the curved road. Provides a median 1 for curved roads.

The drainage frame 3 may have a support anchor 4 attached to both sides thereof with a separator base surface or a center separator support anchor.

4: anchor

In FIG. 1, the central separator 1 is a quick drainage type central separator suitable for curved roads such as automobile-only roads or highways, and is characterized by having a drain hole 2 at the bottom of the central separator grounded on the road surface of the center line of the road. These drains (2) is obtained by installing concrete after installing the drain frame (3) at regular intervals in the field, and after the concrete is cured to remove the separation frame or to be integrated with the central separator.

2 is an example of the drainage mold 3, which is a corrosion-resistant steel sheet, It is bent to have a cross section of the back. It is also possible to use a rectangular cross section, but the lower side open type is advantageous in terms of material saving dimension and reinforcing fixing force on the road surface.

3 is a drainage frame 3a which welds the anchor 4 to the side to simultaneously increase the bearing capacity for the road surface and the bearing capacity of the median separator 1. The anchor 4 is for ground, for median, for ground and median. The figure shows the drainage frame 3a to which the ground and the median anchor 4 are applied.

First, drainage frames 3 and 3a are arranged at regular intervals (about 1.5 m apart) on the center line of the curved road section. At this time, the drain frame (3, 3a) is disposed radially so that the center line (S) toward the center of the radius of rotation of the curved road.

In the case of the anchor 4 integral drainage frame 3a as shown in the example, the downwardly projecting anchor portion 4a is driven into the ground to stabilize the drainage frame 3a, and the concrete is poured to build the central separator 1. The upper anchor portion 4b is buried in the concrete to exert the supporting force.

When the drainage frame (3, 3a) is arranged and the reinforcing bar of the central separator along the road direction on both sides of the drainage frame (3,3a) and the concrete is poured and cured to integrate with the central separator as shown in Figure 4 2) A median separator 1 in the form of a radial arrangement toward the center of the radius of rotation of the curved road is completed. At this time, the rainwater falling on the lane (a) having a large radius of rotation of the curved road is collected in the central separator 1 along the road surface and immediately flows down to the lane (b) having a small radius of rotation through the close drain 2.

Fig. 5 shows a cross section when the central separator 1 is constructed on a curved road using the anchor 4 integral drainage frame 3a. In this case, the anchor for supporting the center separator itself is omitted in the drawings.

Therefore, if the central separator is installed on a curved road with a predetermined slope toward a lane with a small radius of rotation, the rainwater of the lane with the large radius of rotation is quickly distributed and drained to the lane with the smaller radius of rotation. Rainwater accumulated in the lanes can have the effect of removing traffic jams that threaten safe driving by splashing water or causing water curtains.
